Rubber Mill Machine

The Rubber Mill Machine is an essential piece of equipment in the rubber processing industry, serving a variety of tasks like heat refining, mixing rubber materials, and masticating raw rubber. It plays an integral part in prepping raw materials for further production processes while assuring efficient blends for various applications.

The open type rubber mixing machine, commonly referred to as an open mixing machine or simply rubber mixing machine, works by cutting and squeezing rubber materials through two horizontally placed rollers which rotate at different linear speeds to enable cutting/squeezing of materials, cutting/squeezing rubber materials as needed, heat refining processes, tablet pressing processes as well as more traditional uses such as mastication/mixing processes and tablet pressing processes.

1. Roller Design and Material

Rubber mill rollers are an integral component of their machine, designed for durability and efficiency. Constructed of chilled alloy cast iron with surface hardness of 70+-2HSD for excellent wear resistance, depths of the chilled layer typically range between 8-22mm for increased longevity and performance during rubber processing.

2. Rolling Bearings and Seals

This machine features high-quality rolling bearings made of high-grade fluorine rubber for smooth and efficient operation while saving power by approximately 5-8%. They're sealed using skeletonless oil seals made of fluorine rubber to provide reliable sealing that keeps oil leakage out even under intense operating temperatures and pressures.

 

3. Roller Bearing Lubrication System

Lubrication systems for roller bearings are an integral component of overall machine performance, including:

These systems of lubrication work by manually using glycerin pumps; electrically using dry oil pumps and thin oil lubrication pumps; or by thin oil lubrication by manually using thin oil pumps to ensure smooth roller operation, minimizing friction and wear for extended bearing lifespan.

4. Bearing Seat, Annealed

The bearing seat is constructed from cast steel and processed through an annealing treatment to improve strength and durability. Equipped with lubricating oil holes for easier and efficient maintenance of roller bearings.

5. Distance Adjustment Device

This machine offers a distance adjustment device, enabling the user to easily set optimal processing conditions by controlling gap between rollers for optimal processing results. Distance can be adjusted via multiple methods:

Users may select the type of adjustment best suited to their rubber mixing process based on specific needs, ensuring maximum flexibility and precision during operation. Manual, Electric or Hydraulic adjustments are all options available to users for selection ensuring flexibility and precision during their rubber mixing processes.

6. Rubber Baffle

To enhance the mixing process, the machine features a rubber baffle which helps manage material flow during operation. There are various configurations of this rubber baffle available.

Fixed type, manual mobile type and hydraulic mobile type machines all offer great versatility to meet a range of rubber mixing tasks.

7. Transmission Mode

The rubber mill machine's transmission system is highly adaptable, offering various configurations to meet specific operational needs:

Single Drive Single Output Shaft and double Drive two output shaft.

Double Drive

Our transmission system utilizes a hard tooth surface reducer with an oil bath lubrication system for reliable performance with low noise levels and lasting durability. Furthermore, this choice of reducer helps the machine operate smoothly under different loads for efficient rubber processing.

8. Roller Temperature Adjustment Device

Temperature control is vital in the rubber mixing process to ensure proper heat refining and mixing of materials, and therefore requires an adjustable roller temperature regulation system composed of rotary joints with nozzles to precisely control roller temperatures. An intelligent temperature controller offers highly accurate temperature regulation to guarantee rubber is processed under optimal thermal conditions.

9. Glue Turning Device

A glue turning device is an optional feature designed to reduce labor and increase overall work efficiency. The device comes in two forms, both designed to save labor.

Hydraulic glue turning (HGT): This feature automates the process of turning rubber material during mixing, eliminating manual intervention and improving overall efficiency in rubber processing.

A Rubber Mill Machine is used in various stages of rubber manufacturing, such as:

Heat refining: An essential step in improving the consistency and quality of rubber materials.

Mixing of Rubber Materials: Blending raw rubber with additives for desired properties is another vital component.

Mastication of raw rubber: Breaking down rubber to enhance its processability for subsequent manufacturing steps.

Tablet pressing: Some configurations of this machine allow users to shape rubber tablets for easier handling and further processing.
